18 Apr 2012 round2 Round input to nearest multiple of arbitrary value. Author: Robert Bemis

Roundn is in the Mapping Toolbox which costs approximately $1,000.00 for a single user license. It is much simpler; however, it has fewer features and costs $1,000.00. The syntax for using roundn is reproduced from the Mathworks website to help anyone who reads this comment thread. Please let me know if a program with the simple syntax of Roundn would be of benefit to the Matlab Central Users Community.

roundn - Round to multiple of 10n
Syntax

roundn(x,n)
Description

roundn(x,n) rounds each element of x to the nearest multiple of 10n. The variable n must be scalar, and integer-valued. For complex x, the imaginary and real parts are rounded independently. For n = 0, roundn gives the same result as round. That is, roundn(x,0) == round(x).

09 Jan 2014 Air Absorption Calculates sound absorption (attenuation) in humid air Author: Edward Zechmann Johannes

according to ISO 9613 error is ~10% for <1MHz. Function is what I've looked for. Thanks.

22 Dec 2013 Impact Isolation Class This program caculates the Impact Isolation Class (IIC) given the input LN values in dB. Author: Edward Zechmann ali

good

09 Dec 2013 Air Absorption Calculates sound absorption (attenuation) in humid air Author: Edward Zechmann Johannes

What is the frequency range for this function? ISO 9613 can be used for maximum 10kHz. I'm looking for a function for ultrasound which has more than 20kHz.

16 Nov 2013 Continuous Sound and Vibration Analysis This program analyzes sound and vibrations data using metrics for continuous noise and vibrations. Author: Edward Zechmann Andrew P

A welcome and powerful tool. Using MATLAB 7.12 but having problems with concatenating arrays

metrics_buf =

line 1401 in Continuous_Sound_and_Vibrations_Analysis.m

Looking forward to performing interesting analyses!
